12 Claims. (01. 259 102) The present invention relates to kitchen and household appliances for use in the mixing and beating of materials, and other operations, involved in the preparation or baking and cooking 5 of foodmaterials, and the primary object of the invention is to devise a practical and eflicient appliance of this character, of durable and inexpensive construction and having instrumentalities of an interchangeable type for adapting the same for various different operating functions.

Accordingly, I have devised an appliance adapted for hand operation, although equally adaptable for motor driven use, and comprising a practical and compactly arranged driving mechanism with which various types of operative attachments may be quickly and conveniently connected for mixing, beating or whipping and the like.

It is also sought to provide an appliance in which the receptacle, provided for containing the materials which are being treated by the device, is of removable cup form having a housing for accommodating the various connections while in operative position.

A further object of the invention is to provide an improved stable form of 'disconnectible drive connection adapted to afford a rigid, and firm connection with smooth and quiet driving action; A novel and improved beating or whipping attachment is also comprised within the main purpose of the invention.

It is also sought to devise a practical and efficient supporting as well as wall-attaching means for mounting the appliance in position for use.

With the foregoing general objects in view, the invention will now be described by reference to the accompanying drawings, illustrating a compact hand-operated device for household use, embodying the various features of improvement, after which those features and combinations which are deemed to be novel and patentable will be set forth and claimed.

Figure l is a front elevation partlyin vertical section and partially broken away, illustrating an appliance constructed in accordance with the present invention;-

Figure 2 is a plan view with the cover member removed and other parts partially broken away;

Figure 3 is a section on line lII-III of Figure 1 one. larger scale;

Figure 4 is a perspective view of the receptacle or cup member;

Figures 5 and 6 are edge and side views, respectively, illustrating a modified form of attachment I for mining or beating operations; and

' central sleeves 34, for slidin Figure 7 is a perspective view showing the clamping member for securing the device to a table or bench.

Referring now to the said drawings in detail, these illustrate the appliance as comprising a hollow body portion 19, and a base member 11, attached thereto by screws 12; Inside the body is formeda block structure 14 to provide a drive for a horizontal shaft 15 having the exterior operating handle 16. The inner end of the shaft 15 carries a gear wheel 17, meshing with a pinion 18, provided on the lower end of a vertical shaft 20, operating in a sleeve bearing or housing 22, projecting upward from the center of the body 10, as illustrated in Figure- 1. The lower end of the shaft 22, has a. knob-like extension 23 engaged by a steel spring plate 24, supported by adjusting screws 25, carried by an adjacent block 26, whereby an upward thrust may be imparted to the shaft 20, and this thrust varied for varying the frictional engagement of the collar or flange 27 on said shaft with the inner face of the body 16, or marginal portion surrounding. the opening into the sleeve bearing 22. By this means the drive connection may be adjusted and any loose play in the pinion 18 and its shaft 20 eliminated. The upper end of the shaft 20, is bifurcated inside the sleeve 22 as indicated at 30, for making detachable driving connection with the tongue 32, of the particular attachment or material treating device which is to be mounted into position for operation. In Figures 1 and 2 this is illustrated as a cream whipping attachment'comprising a pair of whipping elements or frames 33 provided with gly engaging the pair of vertical shafts 35, to the lower ends of which said frames are detachably threaded as indicated at .36. The upper ends of the shafts 35 are provided. with gears 37 having hub portions 38 journaled in the end portions of a bar or plate 39, andretained in connection therewith by screws 40 and washers 41. The ends of the bar 39 rest on spacer blocks '42 mounted in.the ends of a housing 43 which is provided with openings 44 for the shaft 35 and also an intermediate opening 45 for the hub flange 46 of a gear wheel 47 resting on the bottom of said housing 43, between the gears 3'7 and meshing therewith. A cap or cover plate 48 is secured by screws 49 over the top of the housing 43.

The drive connection to this cream whipping device is made by means of a stem 50 projecting down from the middle portion of the bar or plate ,29, and formed with the tongue 32 which engages the forked portion 30 of the pinion shaft 20 in- 110 side the sleeve 22, the stem having a shoulder 52 adapted to function as a limiting stop by engagement with the upper end of said sleeve; prior to such engagement it will be understood that the spring member 24 provides a yielding support for the shaft 20, and'other parts connected therewith, includingthe elements of the mixing or beating attachment.

The top face of the body 10 forms a flat supporting surface on which to set the receptacle or cup member 54 having a convenient handle 53,

and also a central upright sleeve or housing 55 for embracing the bearing sleeve 22. The upper end of the sleeve 55 enters the annular space between the top of the stem and the flange hub 46 of the gear 4'1, so that this interfitted relation of the parts provides a firm and s'ubstansecurely to the top surface of the bench or table.

tially rigid bearing structure for the support and drive of the attachment in a quiet smooth manner without any lost motion between the parts. The upper end of the sleeve is also formed with a pair of notches or recesses 56, for engagement with lugs 57 (see Figures 2 and 3) projecting in ward from the hub portion of the gear 47, whereby the latter is maintained stationary as required for the operation of the cream whipping device. In this operation,'the stem 50 and bar 39 are rotated by the shaft 20, carryingthe gears 3'1 around the fixed gear 4'1 in planetary fashion, and thereby imparting rapid simultaneous rotating motion to the whipping elements 30 in the same direction about their separate individual shafts 35. The direction of the thread provided at 36 is opposite to the direction of this rotation, to prevent unscrewing of the frames 33 from the shafts 35. The cup 54 is removable as shown in Figure 6, andwhen mounted in operative position upon the body 10, the handle 53 may be left in either right or left hand position (compare Figures 1 and 2).

For the cup or receptacle a cover member 60 is provided having a central opening 62 of appropriate size, and a marginal flange 63 adapted to set inside the upper edge of the receptacle or cup member 54, as illustrated in Figure l.

It is apparent that the pinion shaft 20, with its bifurcated end 30, is adaptable for interchangeable use for the driving of different types of attachments, having the same form of stem for connection with said shaft, as for example, the mixing, beating, 'or stirring device shown in Figures 5 and 6, comprising the frame 64, with fingers 65, and stem 66, adapted for entering the sleeve 22 and formed with the tongue 32' for engagement with the fork 30. The stem 66 is also formed with the shoulder 52' as well as with a flange 46' to provide the annular housing space for embracing the upper end of the cup sleeve 55, as in the cream whipping form of the attachment.

The appliance may be supported without any fastening means, as upon the top of a table or the like, butmay also be conveniently supplied with clamping or securing means for attachment to either a horizontal or vertical surface. I have illustrated the base member 11 provided with an oblong opening 68, for entry of a lock bar 70 on or opening 68 so as to engage the inner face of the base member 11', and then tightening of the nut '14 eflects'a secure clamping action for holding the appliance in fixed position. An index element may be fitted to the outer end of the screw '11, such as a .plate '15, .for indicating the position of the bar '10 with reference to the opening 68;

A similar locking contrivance may be provided for attaching the vertical bracket arm '16 to a fixed wall plate '17, the parts '16 and '17 being each formed with a boss '18, and the rear boss cut with an oblong opening 68' for the bar '10, and the other locking parts being practically the same as just described.

For attaching to a table or bench, the bracket device, such as illustrated in Figure '1, may be employed, comprising the U-clamp member 80, one arm of which is'provided with a stem 81, carrying the locking bar '10, adapted for insertion through the opening 68, whereby turning of the screw 83 will operate to clamp the base member 11 ring a smooth driving action, free from vibration.

A yielding support for the drive structure and the attachments connected therewith is also provided by the spring plate 24, which is also adjustable to vary the frictional' action produced by engagement ofthe collar or flange 2'1 with the adiacent surface of the body member 10. A most effective and speedy cream whipping action is produced by the described beating or whipping appliance, which is, of course, well adapted for the whipping of other materials, such as mayonnaise, French dressing, etc., in the same manner. The interchangeable feature is of decided advantage, allowing the quick and convenient interchange of attachments for other operations, such as the mixing or heating device shown in Figures 5-8 (for mixing materials such as cake batter, etc.) and other attachments of various types which may be provided with the same stem of tongue structure 5032, for connection with the drive or pinion shaft.

The means provided for securing the appliance in fixed position upon a bracket, table, or wall surface affords a quick acting and secure fastening means for this purpose. It is also apparent that the appliance may be manufactured in any desiredsize according to requirements, as well as adapted for motor driven use if desired.

While I have illustrated and described what I regard as the preferred and most practical form of construction for embodying the various features of improvement, I. desire to be understood as expressly reserving the right to make all changes and modifications which fairly fall within the scope of the appended claims.
